Portland Design Works Sparrow bottle cage
Once upon a time, the old version of this (then called the Bird Cage) attempted to murder Zach Gallardo. Seriously, Google it! Since then, PDW has redesigned it to make it less threatening (though still reasonably dangerous. Ba-dum-tss!)
Cut from lightweight 5052 alloy, its wings fold in to securely cradle and protect your water bottle.
